How gun sounds work In PUBG

• Most of our weapons are supersonic. This means that you will hear the crack/whizz before you hear the actual gunshot

In a scenario where you see a shooter 1000m away, using AWM (>900m/s muzzle velocity) the events will occur in such order:

1. You see the muzzle flash

2. After ~1 sec you hear the crack/whizz (assuming no air drag)

3. After ~3 sec you hear the gunshot

• Bullets passing close to the player will generate a crack sound, the ones passing further away will only generate whizz effect
• We blend between different sound samples based on distance (the maximum distance and attenuation characteristic is also affected by suppressor attachment). The close gunshot sounds louder and more clear than the distant one

In the current public build, all bullets generate a sound crack effect. We've changed this mechanic by adding a velocity check, so bullets travelling slower than speed of sound will not generate the crack effect but just whizz. - Marek http://www.playbattlegrounds.com/news/65.pu
